摘要：To provide a sialon-based phosphor capable of forming a thin film by mixing it

with a resin, and giving a uniform photoluminescent light with high light emissionintensity, and to provide a method for producing a sialon-based phosphor not havingexcessively large agglomerated particles and a wide particle size distribution, there isprovided a method for producing an α-sialon based phosphor represented by theformula:          MxLnySi12-(m+n)Al(m+n)OnN16-n wherein M is at least onemetal selected from Ca, Mg, Y and Li, Ln is at least one lanthanide metal selected fromEu, Dy, Er, Tb, Yb and Ce, ax+by=m (assuming that the valence of metal M is a and thevalence of lanthanide metal Ln is b), 0
